P(a) = 0.60, p(b) = 0.30, and p( a and b) = 0.15. what is p(a or b)?

A. 0.75

Step-by-step explanation:

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.60 + 0.30 - 0.15

P(A or B) = 0.75

Option A is correct

= 0.75

Step-by-step explanation:

Given that:

P(A) = 0.60, P(B) = 0.30, and P( A and B) = 0.15.

Using the formula:

Substitute the given values we have;

⇒

Therefore, the value of is, 0.75

its not b
